A further object of the invention resides in the construction of the cross head for receiving and distributing lubricant to the cross head guides and connection between the cross head and driving means therefor.

I A further object of the invention is to provide, in a manner ashereinafter set forth, va'wind mill, including a revoluble mill head provided With-a pair of cross head guides and with one of said guides constructed and 20 arranged to provide a lubricant supply pump for the purpose of supplying lubricant to the cross head, guides therefor and pitman con- "nection for the cross head durlng the reciprocation of the latter.

Further objects of the invention are to provide, in a manner as hereinafter set forth, in a wind mill, 9. combined operating and lubricant supply means for the pump rod or load shaft which is simple in its construc- 30 tion and arrangement, strong, durable, compact, thoroughly efiicient in its use, readily assembled, and comparatively inexpensive to manufacture.

With the foregoing and other objects in 3| view the invention consists of the novel construction, combination and arrangement of' parts, as hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown an embodiment of the mvention, but it is to be understood a section on line 2-2 'Figor load shaft 6 of channel form. Fixedly secured to the to 3 by hold fast devices 7 is a base plate 8 aving an upstanding central portion 9 formed with an opening 10 which alines with the opening 4. The top edge of the upstanding portion 9 of the base plate 8 is grooved,.as at 11 to provide a race for hearing balls 12. Supported uponthe balls 12 is a capmember 13 having its lower end provided with an annular flange 1a which extends laterally therefrom, and has a depending outer portion 15 which is spaced from the casing 5. The lower face of thecap member 13 is formed with a groove 16 which opposes the groove 11 and receives the bearing balls-12. The flange 14 is ported, as at 17 for the purpose of supplying lubricant to the balls 12. he upstanding portion 9, in connection wlth the cap member 13 and bearing balls 12, con- StltllteS a bearing for the revoluble mlll head,

' which is referred to generally by the reference character 18.

As is well known, in the art of wind mills, the pump rod or load shaft is operated from a rec'iprocatorycross head riven from a pair of spur gears operated by a pair of spur pinions mounted on the horizontal shaft 19 which carries the wind wheel 29. Only one spur pinion and spur gear is shown. The shaft for the spur gears is indicated at 21. A spur pinion is indicated at 22 and spur gear at 23. The shafts 19 and 21 are provided with bearings 24, 25 respectively. A

wind vane is indicated at 26 andwhich is carried by a pivoted, spring controlled supporting structure 27 connected to the mil head. The shaft 19 projects from one side of the mill head and has the wind wheel 20 connected upon the outer end thereof.

The mill head 18 comprises'a lower or container section 28 and an upper or cover section 29. The section 28 is ormed with a depending hub 30, which in connection with the member 13 provides what may be termed a turn table. The section 28 has arranged therein an upstanding tubular part 31 which forms a continuation of the hub and formed inte ra'l therewith are upper and lower horizonta ly disposed tubular suports 32, 33 respectively. The support 32 has the bearings 25 arranged therein and the support 33 has the bearings 24 arranged therein; The supports 32 and ,33 are arranged on opposite sides of the tubular support 31. IDtGlPOSGCl between the tubular support 32 and support 31' is a lateral extension 34 arranged at the upper end of the support 31 and which is formed with a vertically disposed opening 25. Formed integral with the top of the support 33 and with one side of the support 31 is an upstanding socket forming member 36, and the socket provided thereby is indicated at 37 The member 36 is formed. with a lateral opening 38 having the wall thereof threaded.

. The support 31 in connection with a part of the section 28 provides a lubricant'well 39.

The section 28 in proximity to hub 31 has a depressed part 40 forming a pocket 41.

The tubular support 33 is extended lateraly as at 33 for supporting the shaft 19. The

l s pport 33 and extension 33 forms an oil we I, and supported from the tubular portion 33 is'a pulley 33" over which travels a cable 33" for pulling the mill out of the wind.

Secured in the socket 37 by the holdfast device 42, is an upstanding cross head guide 7 and extending through the opening 35 well as being secured therein and to the O0 43, of appropriate height, and constructed preferably of a solid bar of cylindrical cross section. Opposing the cross head guide 43 tom of the pocket 41, is a combined cross head mic and lubricant supply pump forme of an outertubular section 44 and an inner reciprocatory tubular section 45 of less length than the section 44. The section 44 at its lower end is formed with a flanged plug 46 provided with a horizontally disposed port 47 and a vertical port 48. The

' port, 47 opens .at diametrically opposed thereof is points with respect to the section 44 in proximity to the bottom thereof. The port 48 opens into the interior of the section 44 and is normally closed by a check valve 49. The section 44' at the upper. terminal por- (provided with a. pair of lengthwise exten ing diametrically opposed weenie slots 50 for the discharge of lubricant taken up from the well 39. The section 45 at its upper end is formed with a diametrically extending pin 51, which is fixedly secured to the section45, below the top edge thereof and said pin 51 extends through the slots 50 and projects a substantial distance laterally with respect to each of said slots. ,Secured within the lower end of the sect-ion 45 is a short, tubular member 52 which establishes communication between the sections 44 and 45 and the upper end of said member 52 is normally closed by a check valve 53. The section 44 is fixedly secured in position and communicates with the pocket 41 whereby on the operation of the section 45, the lubricant will be drawn into the section 44 when the section 45 moves upwardly and when the latter moves downwardly the section 44, will be closed to the pocket 41, but the lubricant drawn into the section 44, will be forced up into the section 45" and be discharged through the slots 50 into the cross head whereby lubrication for the latter will be had and for other purposes to be presently referred to.

A reciprocatory cross head is referred to generally by the reference character 54 and it comprises a body portion 55 having a cup-shaped top 56 and a pair of vertically disposed openings 57, 58 which openinto the cup-shaped top 56. The body portion 55 is furthermore provided with a horizontally disposed opening 59, the bottom wall of which is formed with a vertically disposed opening 60 and the top wall with a depending transversely extending tubular portion 61'. The cup-shaped top 56 of the body portion 55 forms a lubricant receiving recess 62, having the bottom 63 thereof inclining downwardly from thelopening 58 towards thecross head guide 43 and the other for the stationary section 44 of the combined guide and lubricant pump. Dependin from the cross head 54 is a coupling mem er 66 for the pump rod or load shaft. 6, and saidmember 66 is formed with a shank 67 which extends upwardly through the opening 60 and carries a securing means ,68 therefor. The member 66 is fixedly secured to the pump rod 6, asat 69 and the said member 66 is formed with a web .70 which extends into the rod 6.

The guide 43 and section 44 of the otherguide are connected together at their'upper ends by a cross piece 71 which is fixedl secured in position. .The section 29 o the mill head 18 is mounted'at its lower end upon the section 28 and extends over the cross piece or bar 71 and is secured therewith by the holdfast device 72. The section 29 provides a cover for the cross headguide, as well as the cross head and the mechanism arranged within the section 28.

Arranged in the tubular part 61 is a bearing sleeve 73, through which extends a pivot pin 74. The pin 74 projects laterally from the tubular part 61, that is from each end of the latter, and has connected to each end the upper end of a pitman. Only one pitman is shown and which is indicated at 75. The pitmans are arranged on the outer sides of the spur gears 23, and only one of the spur gears is shown, and the lower end of: the pitman 7,5 is pivotally connected to a spur gear 23,.as at 76.

The pin 51 is engaged by the cross head '54 on the upward movement thereof, whereby the inner section 45 of the combined guide and lubricant pump is elevated. The section 45 provides what may be termed .a hollow piston or rather hollow pump piston and operates to draw the lubricant into the section 44 and further operates to conduct the lubricant to the slots 50, so that it will be discharged into the recess 62 and when discharged in the latter it will not only lu-.

bricate the cross head and cross head guides, but also lubricate the connection between the pitmans and the cross'head.

It is thought the many advantages of a wind mill, constructed in accordance with this invention, can be'readily understood, and although the preferred embodiment of the invention is as illustrated and described,

yet it isto be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.
